If you have any Blue Bell cookie dough ice cream in your freezer, put down the spoon. The ice cream company just issued a recall for possible Listeria contamination—the ice cream company’s second Listeria scare in as many years.

There’s also another growing trend, though, besides your grocer’s freezer section, you can spot in this recall—and this one is actually good news. Just like Eggo waffles, which recalled 100,000 whole wheat waffles (seriously, if you still have some, don’t eat them) a few days back, this recall was issued before anyone got sick instead of after being traced back.

Listeria can be incredibly difficult to track down. Not only does it thrive in cold temperatures, it can also linger on almost any surface it touches—countertops, conveyer belts, inside of transport trucks—which then touches food, recontaminating it. And, although symptoms can pop up within a couple days of being exposed, it can also take as long as two months between eating something contaminated with Listeria and finally starting to get sick. This all means that, by the time people are getting sick, it can take a massive effort to track and stop the source of Listeria.
